To start off, what the hell are some people thinking? The PO said "just did the tune up with all new parts'. The condenser had a splice inside the dist, the outside line was so age cracked I think it was the original 74, .35 gap on the plugs, tip on rotor was almost gone, no gaskets on the sump screen just silly cone and judging from the amount of shit inside it had never been cleaned, Weber carb with a Holley choke and believe it or not with 2" screws that big bastard will fit but it might be the cause of my erratic 2500 rpm revs at warm up, remnants of years of wiring removed to the tune of about 4lbs, valve measurements all up and down the scale and the little rat in the engine was the squeak, squeak, squeak from the never greased cam lobes in the distributor . Rants over, question:

1. On that POS Pinto Weber carb I only get spray on the front most throat. The rear has a small drip when the throttle is fully engaged. Is that how they work?

2. I have your standard blackish, dry build up on 1 and 3 but 2 and 4 have a red build up. Looks like rust. Is it?

3. From the manifold there is a hose that runs all the way up to the brake booster. What is it and what does it do?

Question 2 - All the plugs should be the same (duh). I doubt it is rust, but it sounds like that side isn't firing right or maybe running lean (?). I have a book with pictures of plugs and what causes each type of coloration. I'll look it up when I get home tonight.

1- Throw that POS off a cliff and get yourself a real carb. I beleive it's a progressive carb and sounds like the secondary or idle jet may be clogged. Personally leaning towards idle based on you're discription of idle problems above.

2- Rust? Never seen a plug that color before. Sure it's not just brown?
